ROLLER ATTACHMENT FOR SKATES.

SPECIFICATION forming part of Letters Patent No. 324,327, dated August l1, 1885. Application filed Api-i114, 1885. (No model.)

To @ZZ-whom t may concern:

Beit known that I, JOHN H. JAOOBY, of the city, county, and State of New York, have invented a new and useful Improvement in Roller Attachments for Skates; and I do here-v by declare that the following is a full and eX- act description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to skates, and has for its object the interchangeable use of a single set of detachable heel, toe, and clamp plates either with rollers to constitute a roller-skate or with a runner to constitute anl ice-skate.

It consists in an attachment for ice-skates constructed of a flat connecting bar or plate fitted with rollers and formed with inwardly-enlarged recesses or notches in its upper edge to receive and engage the bolts by which the detachable hee1,toe, and clamp plates of the iceskate are secured to its runner, and with alug or tenen projecting from said upper edge at the front end of the bar to fit into a recess or mortise vin the toe-plate, whereby said heel, toe, and clamp plates may be as readily and firmly attached to the roller-connecting bar as to the ice-runner, and the necessity of two independent pair of skates for use on a floor or on the ice is avoided.

In the accompanying drawings, Figure l is a side elevation of my improved roller attach ment for ice-skates,with a set of toe and heel plates and clamping devices to be used therewith,or with aniceskate, detached and shown in perspective above it. Fig. 2represents my improved roller attachment with the heel,toe, and clamping plates detached from the runner of an ice-skate, and iitted thereto to form a complete roller-skate.

Arepresents the connecting-bar or runner of a roller-skate, and B B the brackets secured thereto, which carry the rollers C C, attached and pivoted in any approved manner. This runner or connecting-bar is made of a plate of steel correspondingin thickness to the runner of an ice-skate, but reduced in length. It is upheld edgewise by and between the brackets B B, which embrace and clamp between them the thickness of the plate. The rollers O C are mounted and secured to the brackets .in any approved manner. The top edge of the bar A is formed with "inwardly-enlarged recesses or notches D and D', adapted to receive the lower heads of the bolts or studs E E', by which the heel and toe plates of the skate are customarily secured to an ice-runner. The forward end of said top edge is also formed with an offset or tenon, F, adapted to enter a mortise in the toe-plate, and the upper surface of the top edge is adapted, as at m m, to afford rm, even support to the heel and toe plates when secured thereon.

G represents the heel-plate of the skate, stamped out of a single piece of metal, with offsets h h cut out and bent downward, the one at its rear end and the other in the middle thereof. These offsets are slitted or notched to embrace closely the top edge and sides of the runner when fitted thereon, as shown in Fig. 2. Vhen thus tted in place on the run ner, the plate is made fast thereto by a double headed bolt, E, led through a hole piercedv centrally through the plate intermediate the offsets h h, and whose outer wide head engages the outer countersunk edge of said hole,` and whose lower head is adapted to enter and fit closely within the notched or inwardly-enlarged recess D. It is admitted into the recess by means of lateral notches t ,cut in the flange of the head, which, when in register with the runner, allow the head to drop down into the free opening d, Fig. l, cut outwardly from the recess D, the bolt being locked in the recess by turning :it so as to bring said notches t' t' at right angles to the length of the runner, as shown in Fig. 2. The bolt E, in conjunction with the offsets h h, will firmly secure the heel-plate G to the runner, and yet permit its ready detachment.

K represents the toe-plate, stamped out of a single plate of metal, and tted with adjustable transverse clamps K K', and which is also formed with slitted offsets h L, similar to the offsets h of the heel-plate G, and which are made to project downward so as to t upon and embrace the top edge and sides of the runner, as shown in Fig. 2. The front or outer end of this toe-plate is adapted to rest upon the front end of the runner, and is provided with a slot or mortise, a, therein to receive the tenen or lug F, projecting from its top edge. When fitted in place upon the runner, with its offsets h h embracing the same IOO and the tenon F projecting through its mortise u, the-detachable toc-plate K is made fast by means ol' a bolt, E', iitted to project 'from the under side ol` a clamping-plate, L. The head of the bolt E corresponds to the lower head of the bolt E, -and is made to iit into the inwardly-enlarged recess D', and is allowed to enter the same by means of notches i `i in the tlange of its head.

The inner end of the clamping-plate L, carrying the bolt F/, is widened and adapted to iit and turn upon the inner end of the toeplate K, and when thus fitted in place its bolt projects through an opening, j, in the toeplate, between its offsets lL h', to engage the rccess D', and thus ll'asteus both plates to the bar A, the bolt serving also as a pivot upon which the plate L may turn.

rIhe plate L is extended to form an arm, M,

serving as a lever by which the plate may be readily turned, and the other end of this lever is inclined downward and formed with two downwardly-projecting ears,*11 r, adapted to embrace between them the edge of the eonnectingbar A, as shown in Fig. 2, when the lever is brought into line over the saine, and thereby lock the lever. rlhe heel and toe plates are connected by an adjustable plate, I?, whose rear end is bent up, as at p in the drawings, to afford a support for the inner front edge of the heel, and whose front end is perforated to receive a bolt, R. (See Fig. 2.) rlhe rear end of the plate is fitted with a T- headed lug, S, projecting from its under side to enter and engage the sides of a longitudi' nal slot, g, in the inner end of the heel-plate G. Vhen thus iitted upon and secured by the lug S to the heel-plaie, the plate l? will project over the clamping-plate L, to which it is secured by the bolt It, which is led through a slot, r. in said plate L, and made fast by a nut, It', (see Fig. 2,) the bolt forming apivotal connection between the plates I and. L, so as to permit the arm of the latter to be swung in and outlrom the runner-bar A, as required for clamping the heel-piece I. to the bootheel. rIhis movement et' the clamping-plaie L is also permitted to open and close the toeplates K K", fitted on the toe-piece, by causing the heads of the bolts by which the toeclamps are fastened to the toc-piece K to pass through slots \V IV in the plate L, and also through slots IV XV in the toeplate K, as is illustrated in Fig. l.

In the use of the attachment the toe, heel, and clamp plates K, G, L, and I), detached from the runner of the ice-skate, are iitted and secured, in manner as described, to the runnerbar A, so that said bar and its rollers may, by means of said plates, be readily attached to the foot ofthe skates.

I do not claim as new the form and construction of the toe, heel, and clamping plates herein described, as such have heretofore been used in combination with the runners ol' ice-skates.

What I claim as new, and desire to secure by Letters Patent, is-

The hercinfdescribed roller attachment l'or an ice-skate, the same consisting of a ilat plate or bar, A, confined edgewise in roller-braek ets B B, and having inwardly-enlarged recesses I) D formed at either end thereof, and a lug or tenen, F, at its forward end, in combination with suitable supporting-surlilces, m 'n1y m, to receive, and, in connection with suitable bolts, E E', secure, the detachable toe, heel, and clamping plates l, G, L, and I of `the ice-skate, all substantially in the manner and for the purpose herein set forth.

In testimony whereofI I have signed my name to this specilieation in the presence nl' two subscribing witnesses.

JOHN HENRY JA (JOUY.
